The opposite of the WikiWord, where a link is manually created by the user. For MediaWiki and BlogText, a link is created with the double square bracket like so:
[[link]]
[[multiple word link]]
[[the real page |what is displayed]]
There is at least one Wiki out there which makes guesses at links, and linkifies regular text without needing CamelCase or manually-specified free links. I don't recall where I saw it, but I made the Compiled Website do that.
